Have you check your ECU ? Any error code ?

Whoa.....that really terrible FC over there. Just for you info, my FC is RM40 for approx 230KM (dated : 6/2/07). Moreover, it's an auto tranny with Open-Pod Filter installed. Btw, mine is a converted 1.6XLI Wira to a 4G93 Engine.

check ur block sensor and gearbox sensor
total sensor to check is 3, 1 in the block and 2 at the gearbox
last time i was having the same problem with my putra as well
RM 80 can take me only 240km
after changing it, no problem anymore

what your FC now sifu ? What year is your putra ?? Errr...where is the sensor at block and gearbox ?? :regular_smile:

wow, that's almost double man.

probably the problem occur due to faulty Air Flow Sensor or maybe due to messy wiring jobs. Maybe due to several other reasons.

It is good for you to send the car to reputable mechs.

As far as I know, 1.5 wire harness do not have Air Flow sensor wiring. 1.5 engines use MAP sensor.

Wah, and i thought my FC was bad?? bro the 120km u tekan habis habis?? my car also bad la RM50 can go around 240-250km oni. :(

Dark Accoon: Can i know what sensor are you talking about?? Air flow sensor? How much is the sensor which you claim that have changed?? for all 3 i meant. thx

:shocked: wah bro..
Ur FC is too much liao le..
Mine is 1km around 18 - 20 cents.. better check it properly.. good luck...

i just drive slowly , 2500rpm then change gear ,no traffic jam at all...wah, ireally wan to cry now...my engine didnt have knock sensor,and my air flow sensor is using code type 445.i just know my ecu under the passenger carpet is mmc 6123,then gear box code is HICO Mf5m222vrxe...help me tis poor boy please...

 

[mag9556]

better change the whole set of wire and put the proper ECU...

 

[DarkAccoon]

1 sensor at the block ( this is located at the back of the block )

2 sensor at the gearbox...... ( at the gearbox lar, both harness together wan )

last time before changing was RM 80 = 240km
after changing and same driving style RM 75 = 450km

but then to know if it is faulty a not, u gotta sent to a mechanic or more like wireman to plug the reader and read it

changing both cost me around RM 160 for the sensor and RM 20 for the labour ( i which i could have done it myself )
oh yeah, for the sensor rite, i think i kena chop wan cause i bought it from the sunway chop shop ( famous for chopping ppl, but heck i was desperate then )

 

[pifecto14]

Worth a try if its around 150bucks... Can cover back in a month or 2, if can get the type of result such as urs :

"Before changing was RM 80 = 240km
After changing and same driving style RM 75 = 450km"

But may i know what car are you driving?? 4g93 putra/GTI??


keith_njt: Perhaps u could look into this as well..

 

[pifecto14]

Darkaccon: I have find out from my mech that there are oni sensor for auto gearbox, manual tarak sensor. And he claims that juz the block sensor would cost more than RM150. Bro u change all 3 sensor for RM160??. So cheap!
